There is provided a microfilm cassette capable of reducing the case size and obtaining a rational arrangement of elements such as reels and photographic roller. The microfilm cassette includes: a case having a substantially rectangular shape as viewed from the top; a supply reel and a take-up reel mounted inside the case and arranged adjacent to each other horizontally in the length side direction of the case; a photographic opening located around the center of one short side of the case; a photographic roller arranged in a position opposite to the photographic opening; and a shutter for opening and closing the photographic opening. The short side of the cassette case on which the photographic opening is located may be bulged and expanded outwardly around the center of the photographic opening, so that the mark taking lens and the image taking lens can be arranged close to each other. Further, a pair of labels may be attached to the case in positions substantially symmetric with respect to the central axis parallel to the long side of the case. The microfilm camera for this microfilm cassette is also provided.
